Muscular pain - ham cures it, perhaps (10)

I believe the answer is:

rheumatics

I'm a little stuck... Click here to teach me more about this clue!

'muscular pain ham cures it perhaps' is the definition.
I can't judge whether this defines the answer.

'ham cures it perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'ham'+'cures'+'it'='hamcuresit'
'hamcuresit' anagrammed gives 'RHEUMATICS'.

Can you help me to learn more?
